Horrifying footage appears to show the moment a Spanish train left the track, killing dozens of people.
At least 80 are reported to have been killed in the crash, near the northern Spanish city of Santiago de Compostela.
Officials said there had been no technical faults with the train, and Spanish reports claimed the train had been travelling above the speed limit.
Now dramatic Youtube footage has emerged, apparently showing the carriages leaving the track as the train came round a bend, and flying into the wall.
